Because the hyrule logo doesn't represent the girl. It just represents the flying mechanic.

I did. sorta.  Theres no over world travel. It will similar to Mario Galaxy 2. Where Link now fly to different zones and leaps from the floating city. I called this far earlier. Though I didn't call the Wings from the Sword. The developers already stated they wanted to make Zelda more accessible. Anoma even hinted about flying when he gave his short story about his son and the Wind Waker series. Boat, Train, Flying? was the line of thought of his son. Though I suspect flight as a gameplay mechanic will be non existence. I suspect it's just a link in the stories.

Then theres the first signs of the "help" system that New Super Mario Brothers Wii has was first indicated with Zelda images. Theres more to this game that we already know if we just add 2 2.  

If Zelda had just separated levels connected through  an hub world a la Mario Galaxy it would be one of the worst Zeldas ever.

ah I cant wait for this game

There will be a fan add-on for Wiimote and Nunchuck: if the player will manage to flap them fast enough to fly, Link will fly too.

Yeah.

Not even a leaked E3 demo of it for the players :

Twilight Princess demo was leaked.

Really?

This made me a bit excited again. If this game has a lot of flying in it, and if the story is like the says (Link is from islands in the sky and is lead to believe that evil rules in the world below) I might get a Wii and this game after all.

Yeah. It was this demo:

Don't know if there are demos for other areas, but that specific one ended up on the internets.
